夹丹者，血热也。在痘之未出时见者，只宜升提发散，而用紫草、升麻、粘子、蝉
蜕、川芎、荆芥、防风、桔梗、干葛之类，痘出而丹自淡。若过用寒凉，则痘必冰伏。
若在痘出三四日间，则宜凉血解毒，而用生地、牛蒡、木通、荆芥、犀角、紫草之类。
然又须看其颜色如何？红紫者，热极也。白者，痰湿也。至于青黑不可为矣，
瘿者，即颐毒也。每有于未痘数日之前，发一小块，色同肌肉，不红不肿不痛，
最宜急治，否则，痘时而加透托，则势先溃烂，痘必伏而不起，甚有至痘八九日间，连
肉跌出此块，而肉无脓汁者，尤极危症，是由虚火挟痰所致，故宜贝母、花粉、甘桔之
类，预为清利解散，以免后患。
夹瘿一症，多属痘毒痰毒凝结而成。有结于颈颈成结于耳后，或结于腋下，大者如
桃，小者如李，初起则症候如常，次必身烙烦渴而变凶危。然痘在三四日而瘿作焉，则
毒随痘泄，脓随痘灌，自可挽全而无害，故治宜攻痘为主。倘瘿在红肿将脓，而痘随标
焉，则毒脓一溃，元气嚣漓，其痘焉能表暴充灌乎？治法惟宜培元补托，兼与消痰解毒
为主。若在七八之期，痘已黄蜡而瘿作焉，则虽溃无妨，但血气重耗之后，大宜保护元
气，佐以消痰解毒耳。
痘夹凡疮，则气血为疮所夺，痘多不能起发成浆。况疮乃阴毒，痘乃阳毒，阳乘乎
阴，遇隙而发，故痘愈密臭炙退燥，玄水不滋，多变焦紫，且卫气易泄，风痒自作升
发，则窍益闰，寒凉痘毒又遏，若是，则治法维何？必先审其患疮之久近，儿质之强
弱，毒势之起伏。如疮已久，而收在或头或足者，则宜封其疮，使气不外泄，则痘自起
自灌。倘疮才起，而周身密布者，则宜解毒凉血，而兼托痘，则痘自鼎峻。炽者和之，
伏者攻之，仍以大补气血为主，使其接续脓浆，而无干枯内攻之患。又有若火炙而无皮
无汁者，是名火灼疮也，尤宜凉血化毒为主。
夹丹，是由于血分热盛所致。在痘疹尚未发出时出现此症，只适宜采用升提发散的方法，使用紫草、升麻、粘子、蝉蜕、川芎、荆芥、防风、桔梗、干葛等药物，待痘疹发出后，丹毒自然消退。如果过度使用寒凉药物，则会导致痘疹被冰伏而难以透发。
若在痘疹发出后的三四天间出现，则适宜采用凉血解毒的方法，使用生地、牛蒡子、木通、荆芥、犀角、紫草等药物。然而，还需要观察其颜色：颜色红紫的，是热邪极盛的表现；颜色白色的，是痰湿阻滞的表现。至于颜色青黑的，则是无法救治的危重症候。
瘿，就是颐毒（颈部毒肿）。往往在出痘前几天，先发作一小块肿块，颜色与肌肉相同，不红不肿不痛，最应当紧急治疗，否则，当痘疹需要透托之时，这块毒肿会先溃烂，导致痘疹伏陷而不能起发，甚至有到痘疹八九天时，连肉带毒肿一起跌出，且肉质没有脓汁的，这是极其危险的病症，这是由于虚火挟带痰浊所致，因此适宜用贝母、花粉、甘草、桔梗等药物，预先进行清利解散的治疗，以免留下后患。
夹瘿这一病症，多属于痘毒与痰毒凝结而成。有的结在颈部，有的结在耳后，或者结在腋下，大的像桃子，小的像李子。初起时症状如常，随后必然会出现身体灼热、烦躁口渴等症状，从而变得凶险危急。如果在痘疹三四天时瘿就发作了，那么毒邪会随着痘疹外泄，脓液也会随着痘疹灌注，自然可以保全性命而无危害，所以治疗应以攻治痘疹为主。倘若瘿处于红肿即将化脓阶段，而痘疹也随之标露，那么毒脓一旦溃破，元气就会极度耗损，痘疹又怎么能表暴充灌呢？治疗方法只宜以培补元气、托毒外出为主，兼用消痰解毒的药物。如果在七八天的时候，痘疹已经呈现黄蜡色而瘿才发作，那么即使溃破也无妨，只是在气血严重消耗之后，非常注重保护元气，辅以消痰解毒即可。
痘疹夹杂凡疮，则气血会被疮疡所掠夺，导致痘疹大多不能起发成浆。况且疮疡属于阴毒，痘疹属于阳毒，阳毒乘袭阴毒，遇到空隙而发作，所以痘疹越密集、气味越臭秽、痂皮脱落干燥，津液就越不滋润，容易多变焦黑紫色，而且卫气容易外泄，风痒自然产生。若强行升发，则毛孔更加开泄，寒凉药物又会遏制痘毒，如果是这样，治疗方法是什么呢？必须先审察患疮时间的长短、患儿体质的强弱、毒势的起伏情况。如果疮疡已久，且收口在头部或足部，则适宜封闭疮口，使气不外泄，那么痘疹自然能起发并灌注脓浆。倘若疮疡刚起，且周身密布，则适宜解毒凉血，并兼以托举痘疹，那么痘疹自然会盛大隆起。炽盛的予以调和，伏匿的予以攻逐，仍然以大补气血为主，使其接续生成脓浆，而没有干枯内攻的祸患。又有那种如同火烤一般无皮无汁的，名叫火灼疮，尤其适宜以凉血化毒为主进行治疗。
Jia Dan (Clasping Erythema) is caused by excessive heat in the blood level. If it appears before the eruption of smallpox, only lifting and dispersing methods should be used, employing herbs such as Arnebiae Radix et Rhizoma (Zicao), Cimicifugae Rhizoma (Shengma), Plantaginis Semen (Nianzi), Bombyx Batryticatus (Chantui), Ligustici Chuanxiong Rhizoma (Chuanxiong), Schizonepetae Herba (Jingjie), Saposhnikoviae Radix (Fangfeng), Platycodonis Radix (Jiegeng), and Puerariae Radix (Gange). Once the smallpox erupts, the erythema will naturally fade. Overuse of cold and bitter drugs will cause the smallpox to be frozen and unable to erupt.
If it occurs three or four days after the eruption, cooling blood and detoxifying methods should be used, employing herbs such as Rehmanniae Radix (Shengdi), Arctii Fructus (Niubangzi), Akebiae Caulis (Mutong), Schizonepetae Herba (Jingjie), Rhinocerotis Cornu (Xijiao), and Arnebiae Radix et Rhizoma (Zicao). However, one must also observe the color: red-purple indicates extreme heat; white indicates phlegm-dampness. As for blue-black, it is incurable.
Ying (Goiter-like swelling), also known as Yi Du (Poison of the Jaw/Neck), often presents as a small lump appearing a few days before smallpox eruption. Its color is similar to normal flesh, without redness, swelling, or pain. It requires urgent treatment; otherwise, when the smallpox needs to be pushed out, this toxic swelling may ulcerate first, causing the smallpox to sink and fail to rise. In severe cases, even on the eighth or ninth day of smallpox, the flesh and swelling may protrude together without pus, which is an extremely critical condition. This is caused by deficiency fire carrying phlegm. Therefore, it is appropriate to use Fritillariae Thunbergii Bulbus (Beimu), Polygonati Odorati Rhizoma (Huafen), Glycyrrhizae Radix et Rhizoma (Gancao), and Platycodonis Radix (Jiegeng) to clear and resolve the condition preemptively to avoid future complications.
The syndrome of Jia Ying (Smallpox with Clasping Goiter) is mostly formed by the coagulation of smallpox toxin and phlegm toxin. It may knot in the neck, behind the ears, or in the axilla, ranging from the size of a peach to a plum. Initially, symptoms are normal, but subsequently, high fever, restlessness, and thirst appear, becoming critical. If Ying appears on the third or fourth day of smallpox, the toxin will discharge with the smallpox, and pus will fill with the eruption, allowing recovery without harm. Thus, treatment should focus on treating the smallpox. If Ying is red, swollen, and about to suppurate while the smallpox is also emerging, once the toxin and pus rupture, the primordial Qi will be severely depleted, making it impossible for the smallpox to fill and erupt. The treatment method should primarily tonify Yuan Qi and support the expulsion of toxins, combined with resolving phlegm and detoxifying. If Ying appears on the seventh or eighth day when the smallpox has turned yellow and waxy, rupture is not harmful, but after significant depletion of blood and Qi, protecting Yuan Qi is paramount, assisted by resolving phlegm and detoxifying.
When smallpox is complicated by Fan Chuang (Ordinary Sores), Qi and Blood are plundered by the sores, preventing the smallpox from rising and forming pus. Since sores belong to Yin toxicity and smallpox belongs to Yang toxicity, Yang attacks Yin, erupting where gaps exist. Consequently, the denser and more odorous the smallpox, and the drier the scabs, the less body fluids nourish the skin, leading to blackening and purpling. Wei Qi easily leaks, causing wind-induced itching. Forced lifting opens the pores further, while cold drugs suppress the toxin. In such cases, how should one treat? One must first assess the duration of the sore, the strength of the child's constitution, and the fluctuation of the toxin. If the sore is old and healing at the head or feet, sealing the sore prevents Qi leakage, allowing the smallpox to rise and fill naturally. If the sore just appeared and is densely distributed over the body, clearing heat, cooling blood, and supporting the smallpox is necessary, so the smallpox will flourish vigorously. Excess heat is harmonized, latent toxin is attacked, all primarily supported by greatly tonifying Qi and Blood to ensure continuous pus formation, avoiding dryness and internal invasion. For those resembling fire-burned skin without epidermis or fluid, named Huo Zhuo Chuang (Fire-Scorched Sore), the primary treatment is cooling blood and transforming toxin.
